Harvest

why flush, try a day or two just normal water.no flush

it looks a bit overly lush so water-only fertigation is probably fine. if in soil it'd probably be okay at this point, but too early for soilless. soil nutes linger longer in substrate. a little more plump and start scoping those trichomes.. 10-14 days sounds right, but you never know. they can suprise you sometimes. when you scope trichomes, only look at the ones on the calyx and scop multiple levels/locations on the plant. You may want something with a little better magnification.

Probably another 10-14 days still to go. Pictures under blurple grow lights are useless for details.
